Abstract: The vehicle body door sealing strip is a key component that ensures the waterproofing and quietness in the interior of the vehicle, and its assembly quality is closely related to the overall sealing performance and noise, vibration, harshness (NVH) performance of the vehicle. The current mainstream vehicle models all use clamp type sealing strips. During the assembly process, production workers initially clamp the sealing strips onto the door frame sheet metal, and then use electric or pneumatic rolling tools to clamp the metal sheets in the sealing strips to ensure a tight fit between the sealing strips and the sheet metal. This article designs and implements a set of automatic rolling equipment for sealing strips, which replaces manual rolling of door sealing strips. By adopting this set of equipment for mass production in the vehicle production factory, the efficiency of the door sealing strip rolling process has been improved, saving 80 s for each vehicle. At the same time, it further improves the stability of the rolling process and reduces the occurrence of quality defects.
